int, char, float, double, and boolean are all "simple" data types.
true
Any data type that can store more than one value is a data structure.
true
A data structure is a data type whose components are smaller data structures and/or simple data types.
true
The first historical data structure is a file.
false
A record is frequently also called a vector.
false
A record is a data structure with one, or more, elements, called fields, of the same or different data types.
true
An array is a data structure with one of more elements of the same or different data types.
false
A file is an external structure with a specified number of elements assigned to an internal file name.
false
The file data structure allows transfer of data between internal and external storage.
true
Records, arrays, and files are all data structures.
true
A stack is a data structure with one of more elements of the same data type.
true
In a stack, all elements are accessed directly.
false
In an array, elements can only be accessed in a LIFO (Last In First Out) manner.
false
A data structure is any data type that stores...
more than one value.
Which is the first historical data structure?
array
The language FORTRAN introduced the...
array
The language COBOL introduced the...
record
What data type is the array index?
integer
What is the index value of the first array element?
0
The record is a data structure that stores...
elements of the same or different data types
The file is a data structure that...
handles storing data to an external file name.
The stack is a data structure that accesses data...
like a LIFO.
In the improved data structure definition what was added to more precisely define a data structure?
the storing and retrieval of data
Write an array declaration for an array named scores, which can store 100 integers.
int scores[] = new int[100];
Write an array declaration, numerals, which stores {'0','1','2','3','4','5','6','7','8','9'}.
char numerals [] = {'0','1','2','3','4','5','6','7','8','9'};
The keyword length indicates...
the number of elements in an array.
A data type whose components are smaller data structures and/or simple data types.
data structure
A data type that only stores a single value.
primitive/simple
Another word for an array.
subscripted variable
Another word for a one-dimensional array.
vector
Another word for a two-dimensional array.
matrix
A data structure with one, or more, elements, called fields, of the same or different types.
record
The index of the first element of an array.
0
The index of the last element of an array.
length - 1
Will tell you how many elements are in an array.
length
If an array of ____ is defined, but the individual elements are not initialized, 0 will be the default value of all the elements.
int
If Java did not have a String data type, the closest substitute would be an array of ____.
char
Similar to an array, but can only access data in a LIFO manner.
stack
An internal data structure assigned to an external file name.
file
Regardless of what an array stores, the index is always this data type.
int
Programming language that introduced arrays.
FORTRAN
Programming language that introduced records.
COBOL
The largest valid index of an array.
length - 1
The smallest valid index of an array.
